MySQL Cluster NDB 7.0.12a was withdrawn shortly after release,
due to Bug #51256. Users of the original 7.0.12 release should
upgrade to MySQL Cluster NDB 7.0.12b, which fixes this issue
(and others). Users of MySQL Cluster NDB 7.0.11 or MySQL
Cluster NDB 7.0.11a should upgrade to MySQL Cluster NDB
7.0.11b, if they have not done so already.

This is a replacement release for MySQL Cluster NDB 7.0.12,
fixing a critical issue in that version that was discovered
shortly after its release (Bug #51027). MySQL Cluster NDB
7.0.12a is identical in all other respects to MySQL Cluster NDB
7.0.12. Users of MySQL Cluster NDB 7.0.12 (only) should upgrade
to the 7.0.12a release as soon as possible.

This is a testing release only, for the purpose of testing the
fix for Bug #49190 (now also incorporating the fix for Bug
#51027). This release is otherwise identical to MySQL Cluster
NDB 7.0.11b; users of MySQL Cluster NDB 7.0.11 or MySQL Cluster
NDB 7.0.11a who are not interested in testing this change should
upgrade to MySQL Cluster NDB 7.0.11b (if they have not done so
already), then wait until MySQL Cluster NDB 7.0.13 becomes
available.

This release incorporates all bugfixes and changes made in
previous MySQL Cluster NDB 7.0 releases, as well as all bugfixes
and feature changes which were added in mainline MySQL 5.1
through MySQL 5.1.41 (see Changes in MySQL 5.1.41 (2009-11-05)).
